hi Mag. i am having real trouble with this one. is this the safe with the button on front that looks like a sunken ball bearing? nothing is responding to cursor action, the button, numbers, nothing. what do i do to get this safe to react? robert.

Yes, that sounds like the one, robert. It's the safe on the table to your left, directly after you enter the workshop.

The clue to opening the laser locked safe can be found on a paper hidden inside the dining room safe. Did you open the dining room safe yet?

The laser safe can still be opened by trial and error, though, as I recall, even if you don't have the clue paper.

The clue was: "Less 8 nm under the upper limit of the buttercup nm."

(Buttercup = Yellow.)

Then from MaG's walkthrough:

Adjusting the number to the known wave lengths of the visible portion of the spectrum on the panel displays the different colors: Violet (400-425), Indigo (426- 446), Blue (447-499), Green (500-569), Yellow (570-592), Orange (593-620) and Red.

Click to reveal..

The 3 digit number should be set to 584. The buttons to press to set are above and below the safe's display panel. You need to patient and wait for the number entries to register. Then the laser light beam will change colour.

Sorry robert, I meant your inventory toolbar. Right click to bring up your inventory bar, and then click on the larger end square at the far left. It brings up your map, and you can switch between the different floor levels to find the safe locations.
